. POST-CLAMP.

Specification of Letters Batent.

PatentedJuly 15, 1919.

Application filed May 21, 1915. Serial No. 29,634.

States, residing at Hortonville, in thecounty of Outagainie, State of VViscons'in, have invented certain new and useful Improvements in Post-Clamps; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in binding clamps and particularly to binding clamps for attachment to posts or poles to prevent the splitting thereof while being driven.

One object of the invention is to provide a novel and simple device of this character which can be quickly and easily applied to or removed from the post, when desired.

Another object is to provide a device of this character which is provided with novel means for tightening the clamp and a section or auxiliary means for further increasing the tension on the device.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a front elevation of the device in applied position,

Fig. 2 is a rear elevation of the same,

Fig. 3 is a top plan view, of the device,

Fig. i is an enlarged horizontal section on the line 44 of Fig. 1,

Fig. 5 is an enlarged vertical section on the line 55 of Fig. l, and

Fig. 6 is an enlarged vertical section on the line 66 of Fig. 1.

Referring particularly to the accompanying drawing, 10 represents a casing of metal which is open through its front and has passed through its closed end the threaded portion 11 of a stem 12. This stem is pro vided on its outer end with a hand wheel 13.

Slidable in the casing is a block 14: through which extends the threaded end of the stem 12. Carried on opposite sides of the block 14 are laterallydirected pins 15 which extend through longitudinal slots 16 in the sides of the casing 10. Engaged pivotally with these pins 15 outwardly of the casing are the arms of a clevis 17, to the bight portion of which is secured one end of a short length of chain 18. Carried by the other end of the casing is a clevis 19 to which is secured one end of a longer chain 22. Car ried by the other end oflthe short chain is a loop 21, this loop being'pivotally connected to a cam lever 23 which is in turn connected to the other end of the longer chain.

In the operation of the device the longer chain is passed around the upper end of the post or pile and then one of the links engaged in the second clevis 19. Then, by turning the stem 12 a block 14 will be moved toward the closed end of the casing and draw on the longer chain through the connection of the shorter chain with the cam lever. Before the stem is turned, the cam lever is thrown on its pivot so as to clamp the chain'around the post. This will give the initial pressure while the screw stem will complete the tight clamping of the chain around the post. I

It will be seen that to release the device from the post it is only necessary to swing the cam lever away from the post, whereupon the chain will be loose enough to permit the same to be readily slipped over the topof the post or loose enough to disengage the link of the chain from the clevis.

What is'claimed is:

l. A device for preventing the splitting of posts or piles while driving the same, consisting of a flexible element for encircling the upper end of the post or pile, and adjustable means detachably connecting adjacent ends of the flexible element for drawing the sarnetightly around the post or pile.

2. A device for preventing the splitting of posts or piles while driving the same,

' consisting of, a chain arranged to encircle vcarried. by the chain the upper end of a post or pile, a casing and detachably and adjnstzibly connected to one end thereof, a slidable block in the casing connected to the other end of the chain, and a screw shaft carried in the casing and threadedly engaged through the block to draw the chain tightly about the post or pile.

In testimony whereof, We affix our signatures in the presence of two Witnesses.
